1 Chapter 1 Introduction This Chapter provides an overview of the Wireless Access Point's features and capabilities. Congratulations on the purchase of your new Wireless Access Point. The Wireless Access Point links your 802.11g or 802.11b Wireless Stations to your wired LAN. The Wireless stations and devices on the wired LAN are then on the same network, and can communicate with each other without regard for whether they are connected to the network via a Wireless or wired connection. Figure 1: Wireless Access Point The auto-sensing capability of the Wireless Access Point allows packet transmission up to 54Mbps for maximum throughput, or automatic speed reduction to lower speeds when the environment does not permit maximum throughput. Features of your Wireless Access Point The Wireless Access Point incorporates many advanced features, carefully designed to provide sophisticated functions while being easy to use. • Standards Compliant. The Wireless Router complies with the IEEE802.11g (DSSS) specifications for Wireless LANs. • Supports both 802.11b and 802.11g Wireless Stations. The 802.11g standard provides for backward compatibility with the 802.11b standard, so both 802.11b and 802.11g Wireless stations can be used simultaneously. • 108Mbps Wireless Connections. On both the 2.4GHz (802.11b & 802.11g) and 5GHz (802.11a) bands, 108Mbps connections are available to compatible clients. • Bridge Mode Support. The Wireless Access Point can operate in Bridge Mode, con-necting to another Access Point. Both PTP (Point to Point) and PTMP (Point to Multi-1

Introduction • Auto Update. The Wireless Access Point can automatically update its firmware, by downloading and installing new firmware from your FTP server. • Command Line Interface. If desired, the command line interface (CLI) can be used for configuration. This provides the possibility of creating scripts to perform common con-figuration changes. • NetBIOS & WINS Support. Support for both NetBIOS broadcast and WINS (Win-dows Internet Naming Service) allows the Wireless Access Point to easily fit into your existing Windows network. • Radius Accounting Support. If you have a Radius Server, you can use it to provide accounting data on Wireless clients. • Syslog Support. If you have a Syslog Server, the Wireless Access Point can send its log data to your Syslog Server. • SNMP Support. SNMP (Simple Network Management Protocol) is supported, allowing you to use a SNMP program to manage the Wireless Access Point. • UAM Support. The Wireless Access Point supports UAM (Universal Access Method), making it suitable for use in Internet cafes and other sites where user access time must be accounted for. • WDS Support. Support for WDS (Wireless Distribution System) allows the Wireless Access Point to act as a Wireless Bridge. Both Point-to-Point and Multi-Point Bridge modes are supported. 3

Wireless Access Point User Guide • This Access Point must have a "client login" on the Radius Server. • Each user must have a "user login" on the Radius Server. • Each user's wireless client must support 802.1x and provide the login data when re-quired. • All data transmission is encrypted using the WPA standard. Keys are automatically generated, so no key input is required. • 802.1x - This uses the 802.1x standard for client authentication, and WEP for data encryp-tion. If possible, you should use WPA-802.1x instead, because WPA encryption is much stronger than WEP encryption. If this option is selected: • This Access Point must have a "client login" on the Radius Server. • Each user must have a "user login" on the Radius Server. • Each user's wireless client must support 802.1x and provide the login data when re-quired. • All data transmission is encrypted using the WEP standard. You only have to select the WEP key size; the WEP key is automatically generated. 20

Setup Security Settings - None Figure 13: Wireless Security - None No security is used. Anyone using the correct SSID can connect to your network. The only settings available from this screen are Radius MAC Authentication and UAM (Universal Access Method). Radius MAC Authentication Radius MAC Authentication provides for MAC address checking which is centralized on your Radius server. If you don't have a Radius Server, you cannot use this feature. Using MAC authentication 1. Ensure the Wireless Access Point can login to your Radius Server. • Add a RADIUS client on the RADIUS server, using the IP address or name of the Wireless Access Point, and the same shared key as entered on the Wireless Access Point. • Ensure the Wireless Access Point has the correct address, port number, and shared key for login to your Radius Server. These parameters are entered either on the Security page, or the Radius-based MAC authentication sub-screen, depending on the security method used. • On the Access Point, enable the Radius-based MAC authentication feature on the screen below. 2. Add Users on the Radius server as required. The username must be the MAC address of the Wireless client you wish to allow, and the password must be blank. 3. When clients try to associate with the Access Point, their MAC address is passed to the Radius Server for authentication. • If successful, “xx:xx:xx:xx:xx:xx MAC authentication” is entered in the log, and client station status would show as “authenticated” on the station list table; • If not successful, “xx:xx:xx:xx:xx:xx MAC authentication failed” is en-tered in the log,, and station status is shown as “authenticating” on the station list table. 21

Wireless Access Point User Guide Radius-based MAC authentication Screen This screen will look different depending on the current security setting. If you have already provided the address of your Radius server, you won't be prompted for it again. Otherwise, you must enter the details of your Radius Server on this screen. Figure 14: Radius-based MAC Authentication Screen Data - Radius-based MAC Authentication Screen Enable ... Enable this if you wish to Radius-based MAC authentication. Radius Server Address If this field is visible, enter the name or IP address of the Radius Server on your network. Radius Port If this field is visible, enter the port number used for connections to the Radius Server. Client Login Name If this field is visible, it displays the name used for the Client Login on the Radius Server. This Login name must be created on the Radius Server. Shared Key If this field is visible, it is used for the Client Login on the Radius Server. Enter the key value to match the value on the Radius Server. WEP Key If this field is visible, it is for the WEP key used to encrypt data transmissions to the Radius Server. Enter the desired key value in HEX, and ensure the Radius Server has the same value. WEP Key Index If this field is visible, select the desired key index. Any value can be used, provided it matches the value on the Radius Server. 22

Setup UAM UAM (Universal Access Method) is intended for use in Internet cafes, Hot Spots, and other sites where the Access Point is used to provide Internet Access. If enabled, then HTTP (TCP, port 80) connections are checked. (UAM only works on HTTP connections; all other traffic is ignored.) If the user has not been authenticated, Internet access is blocked, and the user is re-directed to another web page. Typically, this web page is on your Web server, and explains how to pay for and obtain Internet access. To use UAM, you need a Radius Server for Authentication. The "Radius Server Setup" must be completed before you can use UAM. The required setup depends on whether you are using “Internal” or “External” authentication. • Internal authentication uses the web page built into the Wireless Access Point. • External authentication uses a web page on your Web server. Generally, you should use External authentication, as this allows you to provide relevant and helpful information to users. UAM authentication - Internal 1. Ensure the Wireless Access Point can login to your Radius Server. • Add a RADIUS client on RADIUS server, using the IP address or name of the Wire-less Access Point, and the same shared key as entered on the Wireless Access Point. • Ensure the Wireless Access Point has the correct address, port number, and shared key for login to your Radius Server. These parameters are entered either on the Secu-rity page, or the UAM sub-screen, depending on the security method used. 2. Add users on your RADIUS server as required, and allow access by these users. 3. Client PCs must have the correct Wireless settings in order to associate with the Wireles Access Point. 4. When an associated client tries to use HTTP (TCP, port 80) connections, they will be re-directed to a user login page. 5. The client (user) must then enter the user name and password, as defined on the Radius Server. (You must provide some system to let users know the correct name and password to use.) 6. If the user name and password is correct, Internet access is allowed. Otherwise, the user remains on the login page. • Clients which pass the authentication are listed as “xx:xx:xx:xx:xx:xx WEB au-thentication” in the log table, and station status would show as “Authenticated” on the station list table. • If a client fails authentication, “xx:xx:xx:xx:xx:xx WEB authentication failed” shown in the log, and station status is shown as “Authenticating” on the sta-tion list table. UAM authentication - External 1. Ensure the Wireless Access Point can login to your Radius Server. • Add a RADIUS client on RADIUS server, using the IP address or name of the Wire-less Access Point, and the same shared key as entered on the Wireless Access Point. • Ensure the Wireless Access Point has the correct address, port number, and shared key for login to your Radius Server. These parameters are entered either on the Secu-rity page, or the UAM sub-screen, depending on the security method used. 2. On your Web Server, create a suitable welcome page. The welcome page must have a link or button to allow the user to input their user name and password on the uamlogon.htm page on the Access Point. 23

Wireless Access Point User Guide 3. On the Access Point’s UAM screen, select External Web-based Authentication, and enter the URL for the welcome page on your Web server. 4. Add users on your RADIUS server as required, and allow access by these users. 5. Client PCs must have the correct Wireless settings in order to associate with the Wireless Access Point. 6. When an associated client tries to use HTTP (TCP, port 80) connections, they will be re-directed to the welcome page on your Web Server. They must then click the link or button in order to reach the Access Point’s login page. 7. The client (user) must then enter the user name and password, as defined on the Radius Server. (You must provide some system to let users know the correct name and password to use.) 8. If the user name and password is correct, Internet access is allowed. Otherwise, the user remains on the login page. • Clients which pass the authentication are listed as “xx:xx:xx:xx:xx:xx WEB au-thentication” in the log table, and station status would show as “Authenticated” on the station list table. • If a client fails authentication, “xx:xx:xx:xx:xx:xx WEB authentication failed” is shown in the log, and station status is shown as “Authenticating” on the station list table. UAM Screen The UAM screen will look different depending on the current security setting. If you have already provided the address of your Radius server, you won't be prompted for it again. Figure 15: UAM Screen Data - UAM Screen Enable Enable this if you wish to use this feature. See the section above for details of using UAM. Internal Web-based Authentication If selected, then when a user first tries to access the Internet, they will be blocked, and re-directed to the built-in login page. The logon data is then sent to the Radius Server for authentication. 24

Setup External Web-based Authentication If selected, then when a user first tries to access the Internet, they will be blocked, and re-directed to the URL below. This needs to be on your own local Web Server. The page must also link back to the built-in login page on this device to complete the login procedure. Login URL Enter the URL of the page on your local Web Server you wish users to see when they attempt to access the Internet, but are not logged in. Login Failure URL Enter the URL of the page on your local Web Server you wish users to see if their login fails. (This may be the same URL as the Login URL). Security Settings - WEP This is the 802.11b standard. Data is encrypted before transmission, but the encryption system is not very strong. Figure 16: WEP Wireless Security 25

Wireless Access Point User Guide Data - WEP Screen WEP Data Encryption Select the desired option, and ensure your Wireless stations have the same setting: • 64 Bit Encryption - Keys are 10 Hex (5 ASCII) characters. • 128 Bit Encryption - Keys are 26 Hex (13 ASCII) characters. • 152 Bit Encryption - Keys are 32 Hex (16 ASCII) characters. Authentication Normally, you can leave this at “Automatic”, so that Wireless Stations can use either method ("Open System" or "Shared Key".). If you wish to use a particular method, select the appropriate value - "Open System" or "Shared Key". All Wireless stations must then be set to use the same method. Key Input Select "Hex" or "ASCII" depending on your input method. (All keys are converted to Hex, ASCII input is only for convenience.) Key Value Enter the key values you wish to use. The default key, selected by the radio button, is required. The other keys are optional. Other stations must have matching key values.

If selected, both Unicast (point-to-point) and multicast (broadcast) transmissions are encrypted using AES. • AES - TKIP - If selected, Unicast (point-to-point) uses AES-CCMP and multicast (broadcast) transmissions are en-crypted using TKIP. Pairwise Key Update This refers to the key used for point-to-point transmissions. Enable this if you want the keys to be updated regularly. Key Lifetime This field determines how often Pairwise keys are dynamically updated. Enter the desired value. Group Key Update This refers to the key used for broadcast transmissions. Enable this if you want the keys to be updated regularly. Key Lifetime This field determines how often the Group key is dynamically updated. Enter the desired value. Update Group key when any membership terminates If enabled, the Group key will be updated whenever any member leaves the group or disassociates from the Access Point. Radius MAC Authentication The current status is displayed. This will always be "Disabled", because Radius MAC Authentication is not available with WPA-PSK. The Configure button for this feature will also be disabled. UAM The current status is displayed. This will always be "Disabled", because UAM is not available with WPA-PSK. The Configure button for this feature will also be disabled. 28

Setup Security Settings - WPA-802.1x This version of WPA requires a Radius Server on your LAN to provide the client authentica-tion according to the 802.1x standard. Data transmissions are encrypted using the WPA standard. If this option is selected: • This Access Point must have a "client login" on the Radius Server. • Each user must have a "user login" on the Radius Server. Normally, a Certificate is used to authenticate each user. See Chapter4 for details of user configuration. • Each user's wireless client must support 802.1x. • All data transmission is encrypted using the WPA standard. Keys are automatically generated, so no key input is required. Figure 18: WPA-802.1x Wireless Security 29

Wireless Access Point User Guide Security Settings - 802.1x This uses the 802.1x standard for client authentication, and WEP for data encryption. If possi-ble, you should use WPA-802.1x instead, because WPA encryption is much stronger than WEP encryption. If this option is selected: • This Access Point must have a "client login" on the Radius Server. • Each user must have a "user login" on the Radius Server. Normally, a Certificate is used to authenticate each user. See Chapter4 for details of user configuration. • Each user's wireless client must support 802.1x. • All data transmission is encrypted using the WEP standard. You only have to select the WEP key size; the WEP key is automatically generated. Figure 19: 802.1x Wireless Security 32

4 Chapter 4 PC and Server Configuration This Chapter details the PC Configuration required for each PC on the local LAN. Overview All Wireless Stations need to have settings which match the Wireless Access Point. These settings depend on the mode in which the Access Point is being used. • If using WEP or WPA-PSK, it is only necessary to ensure that each Wireless station's settings match those of the Wireless Access Point, as described below. • For WPA-802.1x and 802.1x modes, configuration is much more complex. The Radius Server must be configured correctly, and setup of each Wireless station is also more com-plex. Using WEP For each of the following items, each Wireless Station must have the same settings as the Wireless Access Point. Mode On each PC, the mode must be set to Infrastructure. SSID (ESSID) This must match the value used on the Wireless Access Point. The default value is wireless Note! The SSID is case sensitive. Wireless Security • Each Wireless station must be set to use WEP data encryption. • The Key size (64 bit, 128 bit, 152 bit) must be set to match the Access Point. • The keys values on the PC must match the key values on the Access Point. Note: On some systems, the key sizes may be shown as 40bit, 104bit, and 128bit instead of 64 bit, 128 bit and 152bit. This difference arises be-cause the key input by the user is 24 bits less than the key size used for encryption. 42

PC and Server Configuration Using WPA-PSK For each of the following items, each Wireless Station must have the same settings as the Wireless Access Point. Mode On each PC, the mode must be set to Infrastructure. SSID (ESSID) This must match the value used on the Wireless Access Point. The default value is wireless Note! The SSID is case sensitive. Wireless Security On each client, Wireless security must be set to WPA-PSK. • The Pre-shared Key entered on the Access Point must also be entered on each Wireless client. • The Encryption method (e.g. TKIP, AES) must be set to match the Access Point. 43

Wireless Access Point User Guide Using WPA-802.1x This is the most secure and most complex system. 802.1x mode provides greater security and centralized management, but it is more complex to configure. Wireless Station Configuration For each of the following items, each Wireless Station must have the same settings as the Wireless Access Point. Mode On each PC, the mode must be set to Infrastructure. SSID (ESSID) This must match the value used on the Wireless Access Point. The default value is wireless Note! The SSID is case sensitive. 802.1x Authentication Each client must obtain a Certificate which is used for authentication for the Radius Server. 802.1x Encryption Typically, EAP-TLS is used. This is a dynamic key system, so keys do NOT have to be entered on each Wireless station. However, you can also use a static WEP key (EAP-MD5); the Wireless Access Point supports both methods simultaneously. Radius Server Configuration If using WPA-802.1x mode, the Radius Server on your network must be configured as follow: • It must provide and accept Certificates for user authentication. • There must be a Client Login for the Wireless Access Point itself. • The Wireless Access Point will use its Default Name as its Client Login name. (How-ever, your Radius server may ignore this and use the IP address instead.) • The Shared Key, set on the Security Screen of the Access Point, must match the Shared Secret value on the Radius Server. • Encryption settings must be correct. 44

PC and Server Configuration 802.1x Server Setup (Windows 2000 Server) This section describes using Microsoft Internet Authentication Server as the Radius Server, since it is the most common Radius Server available that supports the EAP-TLS authentication method.

PC and Server Configuration Using 802.1x Mode (without WPA) This is very similar to using WPA-802.1x. The only difference is that on your client, you must NOT enable the setting The key is pro-vided for me automatically. Instead, you must enter the WEP key manually, ensuring it matches the WEP key used on the Access Point. Figure 48: Properties Screen Note: On some systems, the "64 bit" WEP key is shown as "40 bit" and the "128 bit" WEP key is shown as "104 bit". This difference arises because the key input by the user is 24 bits less than the key size used for encryption. 61

Wireless Access Point User Guide Rogue APs A "Rouge AP" is an Access Point which should not be in use, and so can be considered to be providing unauthorized access to your LAN. This Access Point can assist to locate 2 types of Rogue APs: • APs which have Wireless security disabled. • APs which are not in the list of valid APs which you have provided. When a Rogue AP is located, it is recorded in the log. If using SNMP, you can also choose to have detection of a Rogue AP generate an SNMP trap. Figure 58: Rogue AP Detection Screen Data - Rogue AP Screen Enable Detection Enable Detection To use this feature, enable the "Enable Rogue AP Detection" checkbox, and select the desired wireless band and time interval. Scan Select the desired Wireless band to scan to Rogue APs and enter the desired time interval between each scan. Detection generates SNMP Trap If using SNMP, checking this option will cause a SNMP trap to be generated whenever a Rogue AP is detected. If not using SNMP, do not enable this option. Rogue Detection No Security If checked, then any AP operating with security disabled is considered to be a Rogue AP. Not in Legal AP List If checked, then any AP not listed in the "Legal AP List" is considered to be a Rogue AP. If checked, you must maintain the Legal AP List. Define Legal AP List Click this button to open a sub-screen where you can modify the "Legal AP List". This list must contain all known APs, so must be kept up to date. 76

B Appendix B Troubleshooting Overview This chapter covers some common problems that may be encountered while using the Wireless Access Point and some possible solutions to them. If you follow the suggested steps and the Wireless Access Point still does not function properly, contact your dealer for further advice. General Problems Problem 1: Can't connect to the Wireless Access Point to configure it. Solution 1: Check the following: • The Wireless Access Point is properly installed, LAN connections are OK, and it is powered ON. Check the LEDs for port status. • Ensure that your PC and the Wireless Access Point are on the same network segment. (If you don't have a router, this must be the case.) • If your PC is set to "Obtain an IP Address automatically" (DHCP client), restart it. • You can use the following method to determine the IP address of the Wireless Access Point, and then try to connect using the IP address, in-stead of the name. To Find the Access Point's IP Address 1. Open a MS-DOS Prompt or Command Prompt Window. 2. Use the Ping command to “ping” the Wireless Access Point. Enter ping followed by the Default Name of the Wireless Access Point. e.g. ping SC003318 3. Check the output of the ping command to determine the IP address of the Wireless Access Point, as shown below. Figure 61: Ping If your PC uses a Fixed (Static) IP address, ensure that it is using an IP Address which is compatible with the Wireless Access Point. (If no DHCP Server is found, the Wireless Access Point will default to an IP Address and Mask of 192.168.0.228 and 255.255.255.0.) On Windows PCs, you can use Control Panel-Network to check the Properties for the TCP/IP protocol. Problem 2: My PC can't connect to the LAN via the Wireless Access Point. 83

Wireless Access Point User Guide Solution 2 Check the following: • The SSID and WEP settings on the PC match the settings on the Wire-less Access Point. • On the PC, the wireless mode is set to "Infrastructure" • If using the Access Control feature, the PC's name and address is in the Trusted Stations list. • If using 802.1x mode, ensure the PC's 802.1x software is configured correctly. See Chapter 4 for details of setup for the Windows XP 802.1x client. If using a different client, refer to the vendor's documentation. 84

C Appendix C Windows TCP/IP Overview Normally, no changes need to be made. • By default, the Wireless Access Point will act as a DHCP client, automatically obtaining a suitable IP Address (and related information) from your DHCP Server. • If using Fixed (specified) IP addresses on your LAN (instead of a DHCP Server), there is no need to change the TCP/IP of each PC. Just configure the Wireless Access Point to match your existing LAN. The following sections provide details about checking the TCP/IP settings for various types of Windows, should that be necessary. Checking TCP/IP Settings - Windows 9x/ME: 1. Select Control Panel - Network. You should see a screen like the following: Figure 62: Network Configuration 2.

D Appendix D About Wireless LANs Overview Wireless networks have their own terms and jargon. It is necessary to understand many of these terms in order to configure and operate a Wireless LAN. Wireless LAN Terminology Modes Wireless LANs can work in either of two (2) modes: • Ad-hoc • Infrastructure Ad-hoc Mode Ad-hoc mode does not require an Access Point or a wired (Ethernet) LAN. Wireless Sta-tions (e.g. notebook PCs with wireless cards) communicate directly with each other. Infrastructure Mode In Infrastructure Mode, one or more Access Points are used to connect Wireless Stations (e.g. Notebook PCs with wireless cards) to a wired (Ethernet) LAN. The Wireless Stations can then access all LAN resources. Access Points can only function in "Infrastructure" mode, and can communicate only with Wireless Stations which are set to "Infrastructure" mode. SSID/ESSID BSS/SSID A group of Wireless Stations and a single Access Point, all using the same ID (SSID), form a Basic Service Set (BSS). Using the same SSID is essential. Devices with different SSIDs are unable to communi-cate with each other. However, some Access Points allow connections from Wireless Stations which have their SSID set to “any” or whose SSID is blank ( null ). ESS/ESSID A group of Wireless Stations, and multiple Access Points, all using the same ID (ESSID), form an Extended Service Set (ESS). Different Access Points within an ESS can use different Channels. To reduce interference, it is recommended that adjacent Access Points SHOULD use different channels. 93

Wireless Access Point User Guide As Wireless Stations are physically moved through the area covered by an ESS, they will automatically change to the Access Point which has the least interference or best perform-ance. This capability is called Roaming. (Access Points do not have or require Roaming capabilities.) Channels The Wireless Channel sets the radio frequency used for communication. • Access Points use a fixed Channel. You can select the Channel used. This allows you to choose a Channel which provides the least interference and best performance. • If using multiple Access Points, it is better if adjacent Access Points use different Chan-nels to reduce interference. The recommended Channel spacing between adjacent Access Points is 5 Channels (e.g. use Channels 1 and 6, or 6 and 11). • In "Infrastructure" mode, Wireless Stations normally scan all Channels, looking for an Access Point. If more than one Access Point can be used, the one with the strongest signal is used. (This can only happen within an ESS.) • If using "Ad-hoc" mode (no Access Point), all Wireless stations should be set to use the same Channel. However, most Wireless stations will still scan all Channels to see if there is an existing "Ad-hoc" group they can join. WEP WEP (Wired Equivalent Privacy) is a standard for encrypting data before it is transmitted. This is desirable because it is impossible to prevent snoopers from receiving any data which is transmitted by your Wireless Stations. But if the data is encrypted, then it is meaningless unless the receiver can decrypt it. If WEP is used, the Wireless Stations and the Wireless Access Point must have the same settings. WPA-PSK Like WEP, data is encrypted before transmission. WPA is more secure than WEP, and should be used if possible. The PSK (Pre-shared Key) must be entered on each Wireless station. The 256Bit encryption key is derived from the PSK, and changes frequently. WPA-802.1x WPA-802.1x - This version of WPA requires a Radius Server on your LAN to provide the client authentication according to the 802.1x standard. Data transmissions are encrypted using the WPA standard. If this option is used: • The Access Point must have a "client login" on the Radius Server. • Each user must have a "user login" on the Radius Server. • Each user's wireless client must support 802.1x and provide the authentication data when required. This is normally done via a digital certificate, so no user action is required. • All data transmission is encrypted using the WPA standard. Keys are automatically generated, so no key input is required. 94

Appendix B - Troubleshooting 802.1x This uses the 802.1x standard for client authentication, and WEP for data encryption. If possi-ble, you should use WPA-802.1x instead, because WPA encryption is much stronger than WEP encryption. If this option is used: • The Access Point must have a "client login" on the Radius Server. • Each user must have a "user login" on the Radius Server. • Each user's wireless client must support 802.1x and provide the login data when required. • All data transmission is encrypted using the WEP standard. You only have to select the WEP key size; the WEP key is automatically generated. 95

E Appendix E Command Line Interface Overview If desired, the Command Line Interface (CLI) can be used for configuration. This creates the possibility of creating scripts to perform common configuration changes. The CLI requires either a Telnet connection or a physical connection from your PC to the serial port (RS232 port) on the Wireless Access Point. Using the CLI - Telnet 1. Start your Telnet client, and establish a connection to the Access Point. e.g. Telnet 192.168.0.228 2. You will be prompted for the user name and password. Enter the same login name and password as used for the HTTP (Web) interface. The default values are admin for the User Name, and password for the Password. 3. Once connected, you can use any of the commands listed in the following Command Reference. Using the CLI - Serial Port 1. Use a standard serial port cable to connect your PC to the serial (RS232) port on the Wireless Access point. 2. Start your communications program. For example, in Windows, use HyperTerminal. (This program may not be installed. If so, you can install it using Start - Settings - Control Panel - Add or Remove Programs. Then select Windows Setup or Add/Remove Windows Com-ponents, depending on your version of Windows.) 3. Configure the connection properties: • Name - use a suitable name, such as “AP” • “Port” or “Connect Using” - Select the Serial Port that the cable is connected to. (Do not select your modem.) • Port Settings - Use 9600, N, 8, 1, with hardware flow control, as shown below. 96
